What are SmartWay Certified Vehicles?

Each model year, EPA rates every new car, truck, and SUV for greenhouse gas and smog-forming emissions on scales of 1-10. To earn the SmartWay designation, a vehicle must receive a combined score from both scales that is much better than the average vehicle. SmartWay Elite certification is given to only those vehicles that attain the highest scores on both scales. SmartWay Elite vehicles are the very best environmental performers.

EPA updates the greenhouse gas and smog rating thresholds annually. We also periodically update the SmartWay criteria so that we can maintain our goal of certifying the top 20 percent cleanest most efficient vehicles.

You can also visit fueleconomy.gov to find a list of SmartWay certified vehicles going back to model year 2000.

Earning SmartWay Certification

SmartWay certification is based on the greenhouse gas (GHG) and smog ratings found on all new vehicle fuel economy labels.

Greenhouse Gas and Smog (Air Pollution) Ratings Required for SmartWay Certification

*Prior to MY 2013, SmartWay was based on the greenhouse gas and air pollution scores found on an earlier version of the Green Vehicle Guide.
